'rippncation-sied rpm e5, isis. semi no. vessie',

`illinois, have iiirenied a certain new and.

useful improvement in Headlights, of which the following is a specification.

My invention -relates to improvement-s in 'headlights and is illustrated diagrainineti cally in one forni in the accompanying drawings, wherein-- Figure l is a front elevation; Fig. 2 is n Ycrtice'l section; Fig. 3 is a horizontal section; Figf is o. det-ail section of the lamp bracketsupport; and Fig. 5 is a section A along line of Fig. :2.

Lilie ports are indicated by the saine letter throughout the several igures.

The integral headlight casing A provided with the flat supporting base A1 has `the flaring,- front. A2. A lens sleeve B is hinged at ll1 on the housin0F A. adapted 'to swing into and engage the iiaring front A2 and carries a. lens or projector B2. il parabolic reflector B3 located Within the housiu;` A und 'concentric with the lens B2 extends fon \\ard as 'for as the flaring front A2. The

"lhe number plates C, C1 on either side of the housing*r are pivotally mounted and provided with locks Q2 to hold them in position. The housing is built out as at C3 to support these nurnhen plates and contnins the light C4 to illuminate them.

A bracket support D is rigidly attached to the. hase of the housing and' is provided with a segmental spherical bearing or surface D1. A ball D? rests on this hearing or surtaceand is adapt-ed to be held in position thereon by a plate D3 having a segmental spherical surface D4 in opposition to the ball. This plete engages a lug D5 projecting from the bracket D on one end and is on the other end held down by the'thuinb screw DG and clamped against the bull.A

A tube Eis slidahle in the sleeve El projecting upwardly from the ball and may if need be slidecleer througlrthe opening E2 inthe ball. A thumb screw "3 is provided to hold the sleeve against movement and pen mit adjustment. An electric light socket E* located on the end' of the sleeve carries the light bulb E5. ril-conductor E leeds from the bulb Eithrough thesleeve E, the .ball lig, out beneath the bracket D, to the hinding posts E on the back of the housing.

it will 'be evident that, `While l here sho" in my drawings an operative device, si.- inany changes might he made i size, shape end arrangement of parts Without depnrtinfr materially from the spirit ci my invention. l Wish therefore, that Any drawings be regarded es in u sense diagrammatic.

The use and operation of my invention are as follows: swung out on its hinge 'to lhermit access te the electric light bulb or to the interior of the reflector for cleaning hurpose's. Adi'ueb ments of the position of the electric light bulb with respect to the parabolic reitlector such as ore absolutely necessary in focusing the light from such electric headlight are permitted by manipulation of the sup port Within the housing beneath the pare bolle reflector, access to this heinec had through the space occnpiedhy the illuminated number plates which may be'sv'vung ont forthat purpose. 'The brochet upon which the lmnp supported is, ofcourse, fixed, but the. lmnp tube or shaft is slidahle inthe ball on. the bracket and may he thus moved to the proper vertical position and locked by the thuno screw. Meanwhile, however, when. the bell clamp is releasedthe lbulb may he moved about in any posi-v tion desired and finally locked in position when correctly placed. Thus absolutely universaladjustment is provided, and the elee- The. lens sleeve may he tric light bulb. may be placed in any desired ltfwill he noted that the lenssleeve 'seats upon the iange about the outer periphery o the parabolic reflector and thus gives e tight ies closure to said reflector about its periphery l :1nd prevents to e large extent the entrance of oreigi'l substances which would be inclined to turnieli the reflector. elliptic opening inv the reflector through which the sleeve or tube supporting the light bulb entes is not large enough to permit any very appreciable circulation o air -the hollow stende-rd is sldably received,

Q. ln a lamp support for a, locoiiot-i've headlight. the combination of a stendaiydto which the lamp is attached with e, socket -comprising e hollow stem in which the standard is slidably received, means to secure the standard in the stem and e hollow. bell, a, perforated plat-e on which' the ball rests, a locking plate above the ball with ineens for clamping the stem upon the ball.
